Advanced Surface / Top Surface
Note
When applying tool radius compensation CUT3DCD in combination with the "Advanced
Surface" or "Top Surface" option (requiring a license), the setting recommendations regarding
"Advanced Surface" / "Top Surface" must be observed.
A special test program is provided in the SIOS portal for checking the set data.

3.13.5.2 Selecting 3D tool radius compensation for the 3D face milling (CUT3DF, CUT3DFS,
CUT3DFF, CUT3DFD)
The 3D tool radius compensation (3D TRC) for the 3D face milling is selected with the modally
effective G command CUT3DF, CUT3DFS, CUT3DFF or CUT3DFD.
The actual activation is performed with G41 or G42
With 3D face milling, the surface normals of the plane to be machined must be defined in order
to calculate the tool radius compensation. This must be performed in the block with G41 or G42
via the A4, B4, C4 and A5, B5, C5 addresses.
The tool radius compensation is deactivated with G40.

Meaning
CUT3DFS: 3D TRC for face milling with constant orientation. The tool
orientation is defined by G17 - G19 and is not influenced by
frames.
CUT3DFF: 3D TRC for face milling with constant orientation. The tool
orientation is the direction defined by G17 - G19 and, in some
cases, rotated by a frame.
CUT3DF: 3D TRC for face milling with orientation change (only with
active 5-axes transformation)
